OK, here's the latest.
I ripped the firmware from my real 13 channel gold card. Using the flash.exe util, I attempted to write it to my bronze card (all my cards are 4.00 primary) and it wouldn't take.
So it appears that for some reason, flash.exe can't write the PDA or FW to a 4.00 card.
THEY STILL CAN BE WRITTEN, just not by this utility.
so, for 4.00, it looks as if the only solution is to hack the Proxim (die! die! die! die!) FW update utility.
Anyone good at disassembling?
